If there isn't a sufficient malty backbone in the recipe the hops will come through more. Whether they're overpowering or not depends on how much you like hops. Keep in mind that hops give you several different things: bitterness, flavor and aroma. Which one of these is too overpowering for you? Also, what size batch are you making and what is your efficiency, these are all factors. I'm pretty sure if it's too hoppy most members on here would take it off you free of charge.

I think you'd really need to post the recipe to get an informed answer. If the three ounces are of hops with low alpha acids, and are added across the boil, then the beer could be fine. Alternatively, if the three ounces are super-high alpha acid hops all boiled for 90 minutes, then it could be fiercely bitter. I don't think 3 oz is a silly amount of hops for a 5 gallon batch - though I'm a bit surprised to see only 6 pounds of grain.

Thanks for the input. The local HB guy on my first batch suggested 6 lbs. I'll start the next with at least 10lbs. By the way the hops were 2 oz cascades 6.3% AA, one at the beginning and one at the end and whole leaf Kent Golding's whole leaf 5.0% AA in the middle. I had 1.032 original gravity before and 1.009 after a 90 min biol. As for getting rid of it I'm doing fine on my own and enjoying it.
